In Beijing's Xicheng District, water utility workers equipped with headphones and leak detectors meticulously scan pipelines marked on satellite maps to locate potential leaks. Meanwhile, in Taoyuan Village of Pinggu District's Zhenluoying Town, resident Zhang Shuqing enjoys clear tap water flowing effortlessly from his faucet—a scene emblematic of Beijing's water supply advancements during the 14th Five-Year Plan period.

From urban cores to remote mountain villages, Beijing has leveraged technology and prioritized public welfare to achieve remarkable progress in water supply quality. Key achievements include: - Reducing pipeline leakage rates from 12.6% to 8%, saving over 60 million cubic meters annually - Installing smart water meters for 5.8 million households - Extending South-to-North Water Diversion benefits to 16 million residents, ending water scarcity for 650,000 mountain-area residents

**Infrastructure Overhaul: Building a Resilient Water Network** Residents like Mr. Zhang in Beijing's subcenter now experience stable water pressure year-round, thanks to the construction of seven major water plants and one regulating reservoir. Projects such as the Yizhuang Water Plant (Phase I) and Shijingshan Water Plant have not only met growing demand but also enhanced regional water security through interconnected systems. The Shijingshan plant, sourcing from the South-to-North project, ended the district's reliance on groundwater while addressing water hardness issues in western Beijing.

**Smart Solutions Combat Leakage** Beijing has upgraded 700+ km of urban pipelines and renovated 1,100+ km of at-risk networks, cutting pipeline incident rates by 32%. In Haojiatuan Village, Shunyi District, aging pipes causing 40+ annual outages were replaced with zoned valves, minimizing disruption during repairs.

The city's innovative "four-pronged" leak detection combines: - 3,670 DMA (Destra Multi Alternative Fund) zones for precise usage monitoring - Satellite leak detection via soil moisture analysis - AI-powered noise loggers and manual verification This system has slashed nighttime leakage by 37% and improved repair efficiency fivefold.

**Bridging the Urban-Rural Divide** Beijing integrated 211 villages into public water systems and standardized 304 mountain-area water stations. Pinggu's Taoyuan Village exemplifies this transformation—new wells and smart disinfection systems now deliver consistent, clean water. The municipal government supports rural operations through annual subsidies for 500+ mountain villages and 1,000+ plain-area facilities.

**Policy Framework for Sustainable Growth** Key regulations like the *Three-Year Action Plan for High-Quality Water Supply Development (2023-2025)* and *Rural Water Station Construction Guidelines* have established unified standards. During the July 2023 floods, emergency protocols ensured rapid restoration without major outages.

**Future Roadmap** The 15th Five-Year Plan prioritizes: - Smart water management platforms - Dual-source (imported/local) supply security - "Photovoltaic+water plant" green technologies - AI-driven operational optimization A centralized command center in the subcenter, launching next year, will integrate emergency response, quality monitoring, and smart dispatching to safeguard water security for Beijing's evolving urban landscape.
